====================================== LONGBOAT KEY TREE REMOVAL REQUIREMENTS ====================================== The Tree Code calls for 2 replacement trees for each tree removed. The replacement trees call for: a tree with a diameter of two inches or more measured 4 1/2 feet above ground level, at least ten feet in height from ground level when planted, and with a height of at least 25 feet with a canopy spread of at least 20 feet at maturity. Three, ten-foot tall palms grouped to create a canopy of not less than 15 feet may be substituted for one mature replacement tree. NOTE: A permit is not required for an improved single-family lot.
